Hello Ivan,
It's been a while since I visited the Ljubicic's site last time in January and am surprised that execept you and me no one else signed in. Hopefully, one nice sunny day, some one may join.
Thank you for the response and information. It is interesting how, in a relatively short time (100 years or so), the people (like me) cannot establish the origin of their roots for sure. As far as I know, (in line with your statement), there are lots of Ljubicic families in Croatia and Serbia. Those who moved out and settle worldwide had to immigrate from somewhere. Too bad no one has, besides the two of us, contributed to the Ljubicic's site.
As for their presence in the North-American continent, I personally do not know of existance of any Ljubicic families.
Again, thank you for responding so promptly. Best regards.
Milan
